Abstract
An automatic timing switch device includes a switch control wheel, a driving assembly, and a plurality of push switches. The switch control wheel includes a plurality of wheel-shaped structures stacked sequentially, wherein each of the wheel-shaped structures has at least one notch formed on an outer periphery of the switch control wheel, and the diameters of the wheel-shaped structures reduce sequentially so that the switch control wheel is in tapered shape. The driving assembly drives the switch control wheel to rotate. The push switches are switched by engaging into or separating from the notches of the wheel-shaped structures as the switch control wheel rotated by the driving assembly. Since the switch control wheel is in a tapered shape, so that the switch control wheel is easily to be formed monolithically and is convenient to be installed to the case of the automatic timing switch device.
